Williams powers past Henin

Holder Serena Williams thrashed world number one Justine Henin 6-2 6-0 to reach the semi-finals of the Sony Ericsson Open.
 
The eighth seed repeated her success over Henin in last year's final but this time the American totally dominated the Belgian, having battled to a three-set win in 2007.
 
The top seed struggled with her service game throughout the 79-minute encounter and double-faulted five times - winning only five of 20 second serve points.
 
Asked if she had expected to win so easily, Williams said: "Not over the number one player in the world who was clearly in the best form last year. Everything worked well for me.
 
"I'm feeling better and I've keeping working hard. Being aggressive and not being 12 feet behind the baseline works."
 
Henin, who came into the match with a 15-2 record for the year, had no answers and looked flat-footed against the barrage of shots and powerful serves Williams brought to the court.
 
The world number eight was broken just once when she double faulted and hit a backhand long from deuce in the fifth game leading 3-1, but she then won all nine remaining games.
 
Williams, whose record is now 12-1 for the season, kept her errors to a minimum at 15 whereas Henin posted 32.
 
The American was also far more effective at the net, winning 12 of 16 points, while Henin barely ventured forward and won only five of nine points when attacking the net.
 
Henin had won the last three meetings with Williams in the quarter-finals of the 2007 French Open, Wimbledon and U.S. Open
